Abstract

Selon l'invention, un dispositif SCADA (14) comprend : un concentrateur de commutation permanent (42) et un concentrateur de commutation de réserve (44) pour relayer une transmission de données entre un générateur d'énergie éolienne (12) et des terminaux installés au niveau d'un dispositif SCADA (16) et entre le générateur d'énergie éolienne (12) et des terminaux client (66) ; et un commutateur de réseau (46) pour effectuer une commutation entre le concentrateur de commutation permanent (42) et le concentrateur de commutation de réserve (44) dans le but de relayer la transmission de données entre le générateur d'énergie éolienne (12) et les terminaux. La commutation par le commutateur de réseau (46) est exécutée par une unité d'entrée/sortie (E/S) distante de réserve (48), qui est connectée au concentrateur de commutation de réserve (44), sur la base d'une instruction de commutation qui est appliquée en provenance du dispositif SCADA par l'intermédiaire du concentrateur de commutation de réserve (44). Ainsi, un échec de transmission de données pouvant être attribué à un dysfonctionnement d'un concentrateur de commutation placé côté générateur d'énergie éolienne est éliminé à distance.
